Though stating sandstone thin-section's clastic constituents of outcrop sandstones and core sandstones,collecting sandstones' clastic constituents datas from Jican1 core、Ji3 core、XijiD2 core and JiD6 core,it's judged to the roke type be detritus feldspar sandstone and feldspathic detritus sandstone of outcrop sandstones and core sandstones in studied layer, the mostly roke being detritus feldspar sandstone.

通过统计46块露头砂岩和13块西风井砂岩薄片的碎屑组分，结合收集的鸡参1井、鸡3井、新鸡D2井和鸡D6井9块砂岩碎屑组分含量数据，判断出研究目的层露头砂岩和岩芯砂岩的岩石类型为岩屑长石砂岩和长石岩屑砂岩，主要为岩屑长石砂岩，两种砂岩的岩石学特征基本一致。
